RCBS Primer Swager Alignment Base

I was tired of pinching my fingers while trying to align the neck of my .223 brass with the inner shaft of the swaging die, and then bringing the ram up to hold the brass while I moved my finger.

Instead, this perfectly aligns a casing to the vertical, allowing you to apply a little lateral pressure at the base to hold it in place, and easily move your finger away from the ram without the case falling or you crushing your finger.

This is currently measured for the .223/300BLK casing and works with 9mm too, but if there is enough interest I can make one for the .308 casing as well.
